 Bitmap SetBitmap = Bitmap.createBitmap(GetBitmap(path));
  
 Rect r = new Rect(0,0,SetBitmap.getWidth(),SetBitmap.getHeight());
  
  
 manager.suggestDesiredDimensions(Width,Height);

  }catch(IOException e){
    ErrorOccured(String.valueOf(e));
  }
}


public Bitmap GetBitmap(String path){

File myFile = new File(path);

int HeightDP = (int)(Height*deviceDensity);
int WidthDP = (int)(Width*deviceDensity);




Options options = new Options();
options.inPreferredConfig = Bitmap.Config.ARGB_8888;
options.inScreenDensity = (int)deviceDensity;
options.inTargetDensity = (int)deviceDensity;
options.inDensity = (int)deviceDensity;
options.inSampleSize = 1;
options.inScaled = true;
Bitmap myBitmap = BitmapFactory.decodeFile(GetAbsolute(path),options);

return myBitmap;
